Anyone know of a place?  So far Big Al's says they do it for around $125 (w/o the drilling which is an additional $25).

 Hey George ... if you DIY it will be alot cheaper
Just goto a glass store and get scrap glass cut to size ( thickness will depend on what type of overflow and current tank size )
I have a small corner overflow with 2 x 2" bulkheads
Most glass stores can also drill tanks as well however you will need  to know if you have tempered glass or not
Cheers
